Progressive Collapsing Foot Deformity
Abstract
Adult-acquired flatfoot deformity is a complex orthopedic condition that was redefined with a new nomenclature and classification system published in 2020. In this article, we critically examine the newly introduced concepts, including the use of weightbearing computed tomography, detailing the changes in terminology and classification of the deformity and their clinical relevance. Additionally, we review current studies that support and refine this classification and identify areas for future research.Downloads
